Put data from y to y-1 based on costumer selection

[Anonymous]

Hello Folks,

Happy new year, i need your help about a tricky subject. My client want's to analyse 2019 data and compare it with 2018. I trying to use DATEADD ou PREVIOUSPERIOD but those formulas based their calculation on system date. so  y = 2020 and y-1 is 2019. 

What formulas can i use for display  "price y-1"  with dynamic date base ? See my sample below

date	price	date y-1	price y-1
01/01/2018	100	01/01/2017
01/01/2019	200	01/01/2018	100
01/01/2020	300	01/01/2019	200

Thanks a lot 🙂

Make sure you have a date calendar defined.

To get the best of the time intelligence function. Make sure you have a date calendar and it has been marked as the date in model view. Also, join it with the date column of your fact/s.

After that try

12 Month behind = CALCULATE(SUM(Sales[Sales Amount]),dateadd(('Date'[Date]),-1,Year))



YTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESYTD(('Date'[Date])))

Last YTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESYTD(dateadd('Date'[Date],-1,Year)))
Last YTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESYTD(ENDOFYEAR(dateadd('Date'[Date],-1,Year))))

MTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESMTD('Date'[Date]))
last MTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESMTD(dateadd('Date'[Date],-1,MONTH)))
last MTD (complete) Sales =  CALCULATE(SUM(Sales[Sales Amount]),DATESMTD(ENDOFMONTH(dateadd('Date'[Date],-1,MONTH))))
last year MTD (complete) Sales =  CALCULATE(SUM(Sales[Sales Amount]),DATESMTD(ENDOFMONTH(dateadd('Date'[Date],-12,MONTH))))

MTD (Year End) Sales =  CALCULATE(SUM(Sales[Sales Amount]),DATESMTD(ENDOFYEAR('Date'[Date])))
MTD (Last Year End) Sales =  CALCULATE(SUM(Sales[Sales Amount]),DATESMTD(ENDOFYEAR(dateadd('Date'[Date],-12,MONTH),"8/31")))


QTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESQTD(('Date'[Date])))

Last QTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESQTD(dateadd('Date'[Date],-1,QUARTER)))
Next QTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESQTD(dateadd('Date'[Date],1,QUARTER)))

Last year same QTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESQTD(dateadd('Date'[Date],-1,Year)))

Hi,

You're right DATEADD() is correct, and to make it work you have to use it inside CALCULATE()

Price LY =

CALCULATE (

    SUM ( [price] ),

    DATEADD ( [Date], -1 , YEAR )

)

Should work 😉 let us know
